    Detects enabling or disabling of Remote Desktop Protocol (RDP) using alternate methods such as WMIC or PowerShell.
    In PowerShell one-liner commands, the "SetAllowTSConnections" method of the "Win32_TerminalServiceSetting" class may be used to enable or disable RDP.
    In WMIC, the "rdtoggle" alias or "Win32_TerminalServiceSetting" class may be used for the same purpose.
